Not really. Ethically a clone is indistinguishable from an identical twin
carried by a different mother, which is already possible today. The clone is
fully human in all ways, just as identical twins are today.

Raising brain-dead humans for replacement parts or cells is an ethical issue,
but whether the humans are clones or not is quite irrelevant to the ethics.
The parts of clones are just easier to use for the cloned; that's all.
